Common reasons why the variable frequency air compressor cannot start normally;
first, if the contactor is not closed, it is mainly the electrical cause of the air compressor
(1) First check whether the power supply of the air compressor is connected correctly, whether the power switch is closed, whether the power fuse is blown, and whether the power supply voltage reaches more than 90% of the rated voltage.
(2) Check whether the components of the air compressor power supply pressure relay are damaged and whether the given value of the pressure relay is appropriate.
(3) Check whether the working medium in the temperature sensor of the air compressor thermostat leaks, whether the parts of the controller are damaged, and whether the temperature indication position is adjusted correctly.
2., if the contactor has been closed and the inverter air compressor cannot be started, it is likely that the motor fails or the air compressor has a mechanical failure;
(1) Check whether the phase sequence of the motor wiring is correct, and use a multimeter to test whether the motor winding is short-circuited or open.
(2) Check whether the running parts of the air compressor are stuck on the shaft due to insufficient lubrication or too small clearance. If there is a phenomenon of holding the shaft or sticking the cylinder, the impurities in the lubricating oil should be removed, the new lubricating oil should be replaced, and the oil path should be smooth.
Oil-free air compressors do not require refueling. Oil-free air compressors are specially designed for oil-free compression. They do not need to use lubricating oil to lubricate mechanical parts during operation. This design ensures that the output of compressed air is completely oil-free, suitable for use on compressed air quality
Oil-free air compressors also need to be drained. The working principle of the oil-free air compressor is mainly to compress the inhaled air through mechanical parts such as pistons, screws or turbines, and then output it as high-pressure gas. In this process, because the air itself contains
Screw air compressor, this small and powerful equipment, is really amazing! It can compress air to a fairly high pressure. However, how much air pressure can be played actually depends on the model and design of the compressor. Generally speaking, screw type
Whether the air compressor oil (oil and gas separator) needs to be replaced every time it is maintained depends on many factors. First of all, the oil and gas separator is an important component that determines the compression quality of air and the energy consumption of the compressor. Its main function is to compress the oil mist in the compressed air
The machining center shall be equipped with an air compressor. The reason is as follows: the machining center is a highly automated machine tool that can perform a variety of complex machining tasks. In the process of processing, it needs a variety of auxiliary equipment to support its operation, and the air compressor is used as a compressor to provide compressed air.
The use time of the air compressor filter element will be affected by many factors, including the quality of the filter element, the working environment and the use of the air compressor. The following are some summaries about the use duration of air compressor filter elements: the use duration of high-quality filter elements: in general work
Permanent magnet air compressor, sounds a bit high-tech flavor! In fact, it is an efficient, energy-saving and environmentally friendly compressed air equipment. Its working principle is very simple, that is, it uses a permanent magnet synchronous motor to drive the compressor. This permanent magnet synchronous motor can be
The air pressure range of the factory air compressor is determined according to the specific application scenario and demand. Generally speaking, the air pressure range is between 0.61.0MPa (610bar). However, it should be noted that this range is not absolute and may be different in actual application.
The nitrogen-making machine can continuously produce nitrogen without interruption, which is mainly due to its design principle, technical characteristics and the stability support of the air circulation system, the specific analysis is as follows: 1. design principle supports the continuous nitrogen-making machine through physical separation technology (such as pressure swing adsorption PS.
To remove the moisture from the air compressor, the following strategies can be adopted: Pre-cooling using cold and heat exchange technology: Pre-cooling the hot compressed air just generated, which helps to reduce the moisture content in the air. By reducing the temperature of the compressed air, you can reduce
